Do the work - maybe I had used T F O'Brien & Co for years. I thought they were expensive but I felt comfortable leaving workers in my home if I had to be out, so that was a big plus. Then about 2 years or so ago I needed a repair on one of my systems. I was told it was the thermostat. Fine. We replaced it. About 3 weeks later it was not working again. Then we replaced something else. And something else. And something else. Finally it seemed to be working. Then about 9 months later the thermostat that they installed went on t... read more

Good Air Conditioning Company Last year our airconditioning unit (central air) died. Someone came out immediately. He was honest and fair. He added more Freon but said we probably would need a new unit next year. And sure enough this summer it died completely. We called and they were able to make an appt. within a week. It was the hottest week of the year and they were busy so a week wasn't unreasonable.

My brother was impressed by their local advertisement. So I called. From the first person to the last person I communicated with, in the company, were kind & warm. Let’s not forget about their expertise & responsiveness. They explained my choices, the cost & the process in a manner I understood without dimming down the info. We ultimately chose to install two new heating units. I would definitely recommend this company!

Extremely professional. Technician arrived on time - wearing his face mask - very thorough examination of 2 HVACs! He discussed a different approach while I'm cleaning filters in between visits from O'Brien Co. The technician, (last name "Clark"), wrote his report and I received a copy. I had a choice about which company to use - and I chose O'Brien & Co based on my past experience with this company. I even purchased 2 HVACs from them last year to replace 2 "old" units (which O'Brien's kept up and running until "age" caused ... read more
